Larry Wall gave a great talk this past Saturday at an undergrad
conference at PLNU. I e-mailed the coordinator of the conference to
see about getting the video recording of his talk, but until then the
slides, a transcription, and an audio recording of the same talk that
he gave at OSDC::Israel is available
[http://wiki.osdc.org.il/index.php/Larry_Wall_-_Present_Continous,_Future_Perfect].
If the video recording turns out to be unavailable, I'll still post a
follow-up to let everyone know.
